Abstract
A one-piece plastic container for carbonated beverages with a footed base structure to support the container in an upright position. The container is manufactured with a reduced amount of plastic material while maintaining performance, particularly stability. Stability is preserved when the container is empty and when filled. The upper portion of the base structure has a strap formation between each circumferentially adjacent pair of feet that is relatively stiff and which communicate at their outer ends with readily deformable areas. When the container is pressurized from the carbonated beverage the areas easily deform and expand to avoid unwanted distortions that commonly occur in other footed container base structures and cause the strap formations to apply an upwardly directed force to the central region of the base structure.
Description
The present invention relates to a kind of soda integral type plastic container, particularly with the molded this container of amount of plastic that reduces with leg type bottom construction.These containers usually but just use biaxially oriented by terephthalic acid ethylene glycol (PET) polyester material and fix that the blowing moulding of its molecular structure makes.
The main difficult point of can and sealing carbonated beverage container is control and reduces because the pressure that soda causes makes the distortion of leg type bottom construction.Under reference conditions, this pressure can surpass 75 pounds per square inch (5 crust).Controlled deformation can not cause various problems.
A problem is, protrude downwards the center of bottom construction, and the leg of supporting can not contact areal of support simultaneously, and this bottom of waving causes that container stability becomes bad.In this case, container by center and two supporting legs on the unsettled a bit position of bevelled.
Another problem be because buckle, container that folding line, bump and leg and sidewall surfaces protrusion etc. cause damages.In some cases, this may cause because the structural failure that the stress of concentrating causes; In other cases, this may cause influencing outward appearance U.S. of container.If container is clashed into, the container that has concentrated stress may break.
Another problem is inconsistently to cause the inconsistent of container filling metal line position because container expands, expand and occur in the bottom structures zone mostly, the conformability of canning line position is important to the customer, because the customer often thinks that canning line is lower than normal place and shows to be provided with and fill or container does not have good seal.
To consider that in addition the container of not filling must be upright in filling mechanical device.The container overturning will produce adverse influence to the cost and the efficient of loading operation during carrying.The roomy position of keeping a foothold with leg of bottom construction, the stability of having promoted container.Other factor that will consider is the area maximization of each leg base that contacts with conveyer or other areal of support.Little leg base is stuck in mechanical device and overturning easily.
Many examples with soda integral type plastic container of leg type bottom construction are arranged in the prior art.In order to succeed, said vesse relies on owing to the big relative heavier container of material thickness in the bottom construction scope.This scheme service property (quality) is resisted distortion, but heavier container often involves great expense.When using these containers of less material manufacture, many problems recited above will take place.This container is often lighter aspect weight, often dwindles the standing place of leg or reduces the area of each leg base, and these usually cause the stability problem before and after can.
Therefore, the optimal leg type carbonated beverage container that provides the roomy standing place of reducing material weight and bottom construction leg and big leg bottom area.Simultaneously according to the carbonic acid pressure control of beverage and the expansion and the distortion of control bottom.So that conformability, face shaping, stability in the canning line position cause that promptly adverse influence does not take place in excessive aspects such as stress concentration.
The invention provides a kind of plastic container that are used for the splendid attire soda, it has the bottom construction that extends from cylinder side wall usually downwards.The shape of bottom construction is to develop into from several different shapes are fused smoothly mutually together.When empty bottle and fill soda or other beverage and when sealing, selected shape should satisfy needed stability, according to carbonation pressure the container shapes that is molded as can be changed into new and meet the requirements fill and seal after container shapes.In fact, container shapes influence that is molded as or the predetermined new shape of filling and seal the back container.
According to the present invention, the trend naturally of utilizing blow molding method the container mould when preform blowup the time, the shape that surface that parison at first the contacts thick slightly container wall of generation obtains to meet the requirements.With regard to container of the present invention, the wall thickness of the center of bottom fuses the adjacent part in banded structure around longitudinal axis, substantially radially extends from the center again.The wall thickness of the wall ratio container side wall of center and the leg base of each downward hollow salient is often thicker.
When supercharging, predetermined ground of the shape of container elder generation is at the scope intramedullary expansion of bottom construction, be expanded to the fused part in bottom of adjacency then, further expansion is to sidewall sections, banded structure is separated the double-type support legs in the circumferencial direction adjacency, banded structure itself is separated by the wedge structure of downward extension partly, and wedge structure also is positioned partially between the adjacent in a circumferential direction paired leg.By above-mentioned separation and neighboring region, the power that acts on the banded structure is assigned on the sidewall equably.When end wise was watched container, preferred banded structure presented the shape that is similar to letter " Y ".
Leg type container good looking appearance of the present invention can both provide the supporting of stable standing position before and after charging, and meets other generally accepted industrial and requirement customer, and alleviates greatly than known previous container aspect weight.
From following narration and with reference to relevant accompanying drawing, the professional and technical personnel will become clearer to other advantage of the present invention, and accompanying drawing is as follows:

Figure 13 is with respect to the graphic representation of the position, center of support legs base under the various stress levels of internal tank.
With reference to accompanying drawing, Fig. 1 illustrates the shape of common whole leg type carbonated beverage container.Usually, such container has 4 main portions, i.e. container neck (1), shoulder (3), sidewall sections (5) and bottom construction (7).Bottom construction (7) commonly used comprises 3,5 or 6 hollow leg outshots (8) that extend with camber line shape from sidewall (5) downwards, for container provides supporting, in the prior art, be commonly referred to as the structure (10) of strengthening rib or recess between any a pair of above-mentioned leg part (8).This banded structure of bottom construction from longitudinal axis (9) center on every side radially outwards and extend upward, and is fused with sidewall (5) with the dome-shaped part of shape (12) at last.For example, be rated for 2 liters common 55 grams or more more that weigh of container.
Usually, the container condition of service of above-mentioned prior art is fine, (for example reduce the container materials used for reducing production costs and be container weight, the container of 2 liters of sizes reduce to 50 the gram or 48 the gram or more still less) time, because the carbonic acid pressure of beverage, container is deformed, influence the aesthetic feeling of stability, durability and the outward appearance of container greatly.These distortion are in leg projection (8).Can cause deletrious surface deflections, folding line and bulging near intermediate structure (10), dome-shaped position (12) and on the surface in longitudinal axis (9) centre bottom zone on every side.These distortion often make structural stress concentrate, if therefore clashed into, the structural stress of concentrating can make the container breach again.
Usually, these containers are made with terephthalic acid polyglycol ester (PET) by the blowing moulding that makes the biaxially oriented and permanent deformation of molecular structure.Other material is polyethylene benzoic ether (PEN) or also can use with terephthaldehyde's ester group and some compounds of benzoic ether sill for example, though big more options above-mentioned material, other material also can be considered.
Plastic container of the present invention have a bottom construction, when reducing the quantity of material manufacturing, enable the generation of controlled distortion, and alleviate the problems referred to above.As shown in Figure 2, this container comprises and shoulder (3) and the container neck (1) that connects, and smoothly and sidewall sections (5) and the shoulder (3) that connects, sidewall sections (5) is more smoothly with leak free bottom construction (7) and connect.This container is empty and fills soda and stable supporting all is provided when sealing.Bottom construction (7) makes might control expansion, makes near the upward circumference area in its lower end that at first occurs in sidewall sections (5).
Also extend internally smoothly downwards from sidewall (5) on every side by being arranged on longitudinal axis (9), minimum three the hollow salients or the leg (35) that terminate in flat basically leg base (11) form bottom construction (7), the leg base contacts the areal of support (not shown) again, therefore, provide supporting for entire container.
Fig. 3 is the backplan of the bottom construction (7) of Fig. 2.What separate adjacent in a circumferential direction every pair of hollow salient (35) is and better rigidity banded structure (13) that banded structure (13) separately forms the banded structure (17) of bifurcated again.When end wise was watched, (Fig. 2) banded structure (17) of banded structure (13) and bifurcated presented the shape that is similar to letter " Y " together.In Fig. 3, the shape and the characteristics of the banded structure (17) of hollow salient (35), leg base (11), banded structure (13) and a pair of bifurcated are repetition five times, and be arranged on equably container center around.Five legs are the preferred embodiments of the present invention, but the professional and technical personnel understands that the present invention does not limit five legs, have also shown the center (14) of bottom construction (7) in Fig. 3.
Like this, each banded structure (13) (14) beginning as can be seen from the center, and between a pair of hollow leg (35) from axis (9) radially outwards with upward to extension.Then, banded structure (13) separates crotched banded structure (17), and banded structure (17) extends up on the position near the lower end of container side wall part (5) by the surface near the bottom the leg (35).When container is filled soda, the surface of bottom construction (7), common place between the banded structure of bifurcated, being called as wedge-like structure (15) sometimes is to expand easily, as being represented by dotted lines in Fig. 5.Banded structure (17) is the comparison rigidity, so just plays the effect of restriction expansion on the surface between the banded structure (17).
Hollow leg (35) preferably is connected to the rounded substantially border of leg base (11) smoothly, as shown in Figure 3 and Figure 4.Distance A (Fig. 3) be from the center of container to the distance of sidewall (5), from container the heart to the outer rim (21) of leg base (11) apart from B preferably distance A 70% or bigger.The configuration of this leg base will be provided as promotes the needed roomy supporting of standing of stability.
Shape (as shown in Figure 4) when the shape of flat basically leg base (11) is manufacturing before the container filling and during the can, cooperates roomy standing place in Fabricating machinery, the stability of container is provided.In case container is filled after soda and the sealing, leg base (11) is controllably expanded the folding line of stability or wrinkle or other distortion that presents somewhat flat semisphere (27) and can not reduce container, above the base shape narrated have circular boundary and more help to realize above-mentioned advantage.
Translate into Fig. 9, the amplifier section of its expression bottom construction of the present invention.Wedge-like structure (15) is connected to sidewall sections (5), and equally spaced locatees in a circumferential direction apart from adjacent a pair of hollow salient (35).The banded structure (17) that is produced bifurcated by wedge-like structure (15) separates banded structure (13), and this helps again the pressure dispersing action on sidewall sections (5).If there is not the banded structure (17) of above-mentioned wedge-like structure (15) and bifurcated, supercharging will be exerted all one's strength on shape (12) the dome-shaped near zone partly that is collected at image pattern 1 prior art.
From the surface, particularly when when cutting apart the imaginary line (39) that bottom construction (7) and sidewall sections (5) form, wedge-like structure (15) (Fig. 9) preferably has a feature of complete del (41).
Fig. 6 illustrates the diapire (29) of bottom construction (7), is illustrated by the broken lines hollow salient (35) and wedge-like structure (15), so that the shape of diapire (29) is described better.Diapire (29) is a shapes of substrates, and hollow salient (35) and wedge-like structure (15) are extended from this base shape, promptly keeps configuration in case extend slightly from diapire (29); However, after container was filled soda and sealing, the configuration of diapire (29) was the important component part of bottom construction configuration.
By the conic section (31) that fall to cut with side angle a smoothly with radius R
1Be connected with sidewall sections (5), conic section (31) is downwards smoothly again with radius R
2And have radius R
3Sphere cut body (33) and be connected and form diapire (29).Radius R
3Can less than, be equal to or greater than size A.The surperficial tangent of body (33) do not cut with sphere in the surface of conic section (31).
Fig. 7 and Fig. 8 are the views of explanation banded structure (13).Fig. 7 is the backplan of the bottom construction identical with Fig. 3 except that leaving out most of outline line of describing shape, and showing the position of transversal 8-8 better, Fig. 8 is expression banded structure (13) and the cross-sectional view that amplifies with the part of the relation of diapire (29) thereof.In fact, banded structure (13) be one adjacent to the transition region that has a radius between the hollow salient (35), and nestle up diapire (29).When watching Fig. 7 and Fig. 8, point (37) is banded structure (13) and the common part of diapire (29) just.
In bottom construction (7), (14) towards the extension of the banded structure (17) of corresponding bifurcated, point (37) has become the track of point from the center along with banded structure (13).The track of the point (37) of each point on the banded structure (17) of bifurcated continuously to incorporate sidewall (5) into.
Consult Fig. 5 now, it is the section drawing of the bottom construction (7) of 5-5 lines in Fig. 2.For clarity, saved thin bilge construction except that the cross section.Equally, also label not all of the duplicate components of the banded structure (17) of hollow salient (35), bifurcated and wedge-like structure (15).An above-mentioned stack features comprises that the banded structure (17) of two bifurcateds repeats five times.Each stack features evenly separates at circumferencial direction.Cross-sectional view clearly illustrates inside face (16) and outside face (18).
As shown in Figure 5, because when soda and supercharging, the neighboring area of bottom construction is expanded easily, presents more level and smooth circle.As new location by dotted line (19) expression outside face (18).Level and smooth degree is decided by beverage institute applied pressure value.Under extremity, the banded structure of bifurcated (17) will become and be difficult for finding out and wedge-like structure (15) will become circular bulge.Seem that this expansion acts on the banded structure (13) of relative rigidity pivotal force, make center (14) be moved downward to corresponding leg base (11) at the very start, when pressure developed into the summit apace, container inside, shoulder (3) and sidewall sections (5) all a little radially expanded outwardly.Center (14) roughly returns to its original position.Each hollow salient (35) presents towards general radial direction extrapolated a little, occurs slightly flattening to banded structure (13).Leg base (11) presents a semi-spherical shape a little, and bottom construction (7) provides stable support of vessel.
Figure 13 is under the stress level of varying level in container, with respect to the graphic representation of the position, center (6,14) of leg base (4,11).When pressure increased, the position, center (6) of the prior art container (Fig. 1) of test reduced reposefully; When pressure increased, the position, center (14) of test chamber of the present invention (Fig. 2) increased before minimizing from the beginning.At room temperature, under the pressure of the standard carbonated beverage container of 75 pounds/in2, (Fig. 2,14) position is roughly the same with position before can in the center.
Fig. 5 a is that it clearly illustrates the position with respect to the banded structure of hollow salient (35) (13) along the section drawing of the bottom construction (7) of 5a among Fig. 2-5a line.The outside face (18) in the cross section 5-5 of dotted line (20) presentation graphs 5, and the explanation banded structure (17) of bifurcated and wedge-like structure (15) are with respect to the relation of banded structure (13) and hollow salient (35).
Figure 10 illustrates wedge-like structure (15) (Fig. 9) and a kind of modification of the banded structure (17) of bifurcated, and wherein two or more less wedge-like structures (15b) are separated into banded structure (13) banded structure (17) of 3 or more bifurcated.
The another kind of structure of Figure 11 and 12 explanation bottom constructions (17).Wherein the banded structure (13) that (14) and sector structure or zone (45) bonded assembly radially extend basically from the center form one with (Fig. 6) the same cross section of diapire (29), the result causes as the mild radius as shown in Figure 12.Also show the hollow salient (35) that is connected with fan-shaped banded structure (45) with a radius.
From top narration as can be seen, the invention provides a kind of can be to reduce the light-duty drinking container that quantity of plastics is made.By providing the container with following characteristics to achieve the above object: this container has circumferentially adjacent double-type leg (35), its qualification and supports comparatively the banded structure of rigidity (13) and by banded structure (13) separately.Every belt structure (13) is from being that the zone (15) that comparatively can be out of shape is substantially radially stretched in the center (14) of the bottom construction at center with longitudinal axis (9), the zone of bottom construction (15) be positioned at leg radially outside, be right after sidewall sections (5), the radial outer end (26) of every belt structure (13) is connected on the banded structure (17) by the separated bifurcated of deformable zone (15).Deformable zone (15) can outwards expansion between the banded structure of bifurcated.Be positioned at the top of the outer end (13a) of banded structure (13) at described deformable zone (15), and extend up to position near the sidewall sections (5) of container.Therefore, the initial internal pressurization of container will deviate from longitudinal axis and radially outwards expand deformable zone (15), this makes comparatively the radial outer end of the banded structure of rigidity (13) deviate from longitudinal axis radially outward, up move again, thereby make the supporting swing of banded structure (13) around its leg, and the longitudinal end of banded structure is substantially up moved towards container neck (1), thereby bottom centre district (14) is moved towards container neck along longitudinal axis (9).
The result who improves container stands on flat surface firmly, makes economy, and adapts to expansion effectively; Simultaneously can resistance to deformation when filling soda.
Though above narration has disclosed the preferred embodiments of the present invention, professional and technical personnel's said structure can be made various changes and not exceed scope of the present invention it.
